Join Cisco for a technical seminar on planning for IPv6 transition. Along with Cisco technical experts and other customers, you will get an in-depth look at planning and technical considerations based on Cisco’s Preserve, Prepare and Prosper strategy. These workshops can accommodate between 40 and 50 people and will begin the week of May 23rd, 2011 and run through June 28th, 2011.
The topics of these technical sessions are as follows:
So, World IPv6 Day is just under a month away. You already have IPv6 connectivity, right? How do you know that everything will work correctly when the big day arrives? You will need to do some testing.
A number of enthusiastic engineers across the world have set up public IPv6 sites that you can use to perform all manner of tests. I would like to tell you about some of my personal favorites, and invite you to tell me about your own. Please note that Cisco manages none of the tools mentioned here, and as such cannot offer any assurances about their suitability for use on your network, so insert your own dire sounding legal disclaimers here before continuing.
Can You Connect?
For a quick “Am I Ready?” test, http:/omgipv6day.com/ provides a simple Yes-or-No assessment of your web browser’s ability to access IPv6 enabled sites on World IPv6 Day. Here is my attempt to connect with an impaired IPv6 tunnel:
As many of you are aware, this week the Interop tradeshow is taking place in Las Vegas.
Did you know that Cisco is the primary sponsor of the show’s InteropNet? InteropNet is a world-class, fully IPv6-enabled network powering the 15,000-attendee and 400-exhibitor tradeshow complete with dual-stack IPv6 capabilities to all capable endpoints. This is the first-ever show network to be “dual-stack” with IPv4 and IPv6 running side-by-side and it highlights Cisco’s IPv6 leadership. For more info on our IPv6 activities, please click here.
In addition, those of you stopping by the Cisco booth (booth 1127) will notice demos of our latest solutions including the new Cisco ISR Cloud Web Security with Cisco ScanSafe solution announced today. This solution seamlessly extends ScanSafe Cloud Web Security to branch offices and provides scalable, centralized Web protection and malware detection on the Cisco ISR G2 branch router and requires no additional hardware.
With this solution, organizations can easily deploy cloud-based Web security and Web usage policies, enabling highly secure local Internet access for all branch offices and users while saving time, money, and resources associated with traditional hardware deployments. The cloud service delivery model and central user account administration also make Cisco ScanSafe easy to deploy, manage and maintain via remote IT staff.

What would you say if I told you that one of the most visited websites on the Internet enabled IPv6 connectivity to their site in the course of an afternoon for zero dollars using existing Cisco hardware? How about if I told you that the site was Facebook? Most people would assume I was joking or exaggerating. However, by using LISP, Cisco Certified Internetworking Expert Donn Lee pulled off this seemingly impossible feat and then presented a paper at the North American Network Operators Group (NANOG) about the experience. You can even watch the video here.
What is LISP?
Let’s start by understanding the problem that LISP solves. An IP address serves two distinct functions: It identifies the endpoint host, but also suggests the location because the high order bits identify the network on which the device is located. If you move a device from one subnet to another, the address has to change since the device location changes. The endpoint identification from the previous location gets lost when the device moves, unless some form of tunneling or mobility protocol is employed.
Cisco Locator/ID Separation Protocol (LISP) is routing architecture that provides new semantics for IP addressing. The current IP routing and addressing architecture uses a single numbering space, the IP address, to express two pieces of information:
The way the device attaches to the network
The LISP routing architecture design separates the device identity, or endpoint identifier (EID), from its location, or routing locator (RLOC), into two different numbering spaces. Splitting EID and RLOC functions yields several advantages.
Check out this video for a quick review of LISP.
Although LISP was designed to deal with the route scalability problem in the Internet, it turns out is has the capability to help with the transition to IP Version 6 (IPv6), the next-generation Internet protocol.
The transition to IPv6 is an immediate challenge facing Public Sector, and specifically Federal customers today due to Government mandates and impending IPv4 address exhaustion for consumers of Government services.
Because IPv6 is not backward compatible with IPv4, and because its deployment and operation are different from that of IPv4, development and implementation of an IPv6 transition strategy is imperative. Many techniques exist to ease the transition to IPv6, and the network-based IPv6 transition techniques can be divided generally into three categories: dual-stack IPv4 and IPv6, IPv6 tunneling, and IPv6 translation.
Each approach has its features, benefits, and limitations; they are not all equivalent in terms of cost, complexity, or capabilities. Most likely, a combination of these techniques will provide the best solution. The role that the Locator/ID Separation Protocol (LISP) being developed by Cisco and the IETF can play in IPv6 transition strategies is documented in this Whitepaper.
Incorporating LISP into an IPv6 transition strategy can simplify the initial rollout of IPv6 by taking advantage of the LISP mechanisms to encapsulate IPv6 host packets within IPv4 headers (or IPv4 host packets within IPv6 headers). For example, you can build IPv6 islands and connect them with existing IPv4 Internet connectivity.
LISP is a Cisco innovation that is being promoted as an open standard. Cisco participates in standards bodies such as the IETF LISP Working Group to develop the LISP architecture.
